General
The function and working of the safety quick-closing valves is conceived such that dangerous operating
conditions are avoided and the system is protected.
If the auxiliary power source fails, the safety quick shut-off valves are closed through spring force.
Closing time is less than 1 second / within 5 seconds during control function.

Note:
Corresponding to DIN EN161, a dirt trap which prevents the penetration of bigger foreign bodies must be
installed before each shut-off device.
At the steam boiler firings, shut-off equipment must be provided in the form of two independent and selfclosing quick shut-off valves as double-actuator, according to TRD.
These valve combinations are normally designed with an intermediate flange (production length 47mm)
including a G1/2 test connection. Further connection options to intermediate flange on request.

Venting production series
In the idle position, venting valves are normally opened through spring force. They are closed by
impacting control air with a separate solenoid valve or by force via the solenoid valve of the first
quick shut-off valve of a valve combination.
Type ZE 40 is a very compact and robust valve which is installed as venting valve between two
automatic shut-off valves.
Note: Type ZE is not suitable for line venting.
Nominal diameter:
G ¾“ inner threads – standard
Nominal pressure:
PN40
Connections:
Inner threads,
flange connections as well as weld-on ends DN15, 20 and 25 are possible
Sealing:
O-ring sealing
Casing material:
Stainless steel X5CrNi18 10 (1.4301)
Permissible operating pressure:
16 bar
Permissible temperatures:
max. 100°C
Weight:

Tightness-control accessory
The tightness-control-device DKG (floating ball principle) supports the optical checking of the shutoff equipment sealing.
If there is leakage in the first quick shut-off valve, the operating medium flows through the tightnesscontrol-device and lifts the fully relieved floated element (indicator). The medium is derived safely on
the outlet side.
